alt Hacker NewsLast time I checked, Barman didn't support backups to S3. That's why (for us) pgBackRest was such a big deal: it could offload full and incremental backups to a basically limitless and reliable medium.
I think (and I'm probably wrong now) that Barman only could push backups to another Linux machine (e.g., EC2 box), so you had to worry about your backup system _on top_ of the main DB.
So I'm really hoping someone will pickup maintaining pgBackRest.

They have a plugin that supports backups to cloud storage

For CNPG: https://github.com/cloudnative-pg/plugin-barman-cloud
Something like Rclone and a cron job, or else s3 mounted via FUSE, could possibly bridge that. Of course then you have to worry about reliability of the bridge...
There are other ways to mount S3, but you may want to check out Amazon's new product, S3 files: https://aws.amazon.com/about-aws/whats-new/2026/04/amazon-s3...
Huh... Opposite experience. Barman cloud (s3 backups) is the only way I've ever used it. I didn't realize it wasn't the only way. Makes sense it could just use a filesystem.
